FIELD OF DISCLOSURE

The present disclosure relates to systems, devices, and methods forinjecting fluid into at least one electrical cable.

BACKGROUND

Typical load and dead break separable connectors or cable terminations(herein referred to as a “separable connectors”) are used to connectmedium or high voltage underground electrical cables to sources ofenergy and or sources of loads. The separable connectors typical includea termination port with an electrical pin or probe (herein referred toas an “electrical probe”) for electrically connecting the electricalcable to the source of energy or load. The separable connector typicallyincludes a connection port through which the electrical cable isinserted to operable connect the electrical cable to the probe.Separable connectors generally have an elbow configuration where theangle between the termination port and the connection port is a rightangle (90°). However, separable connectors can have otherconfigurations, such as a “T” type or even a “live front” configuration.There are at least two (2) types of elbow applications: load break anddead break.

For example, the systems, devices, and methods canprovide for injecting an electrical cable with a fluid when theelectrical cable is affixed to an existing separable connector (e.g.,elbow connector). The existing separable connector may or may not have aspecial modification for a fluid injection system via an access portdisposed between the termination port and the connection port. However,exemplary embodiments do not require the access port, but ratherfacilitate injection of fluid into the electrical cable via thetermination port.

In accordance with embodiments of the present disclosure, the separableconnector can be removed from the source or load and the existingelectrical probe can be removed from the separable connector. An adapterprobe can be configured and adapted to interface with the separableconnector and replace the removed electrical probe. The adapter probecan facilitate connection of the separable connector to a fluidinjection system. The adapter probe can include a distal end and aproximal end, and can include a passageway that extends at leastpartially between the distal end and the proximal end. The distal endand/or the proximal end may include features/elements for connectingwith an adjacent device (e.g., connector, hose, pipe, adapter, junction,fluid feed tank, conduit, discard/vacuum tank). The separable connectorwith the adapter probe installed therein can be connected to a fluidfeed tank at one end of the electrical cable to place the electricalcable in fluid communication with a fluid feed tank via separableconnector and the adapter probe. At the other end of the electricalcable, another separable connector with the adapter probe in place ofthe electrical probe can be connected to a discard/vacuum tank to placethe electrical cable in fluid communication with a discard/vacuum tankvia the separable connector with the adapter probe.

In accordance with exemplary embodiments of the present disclosure, amethod for introducing fluid to an electrical cable is disclosed. Themethod can include (i) disconnecting a termination port of a separableconnector from a source of energy; (ii) removing an electrical probefrom the termination port of the separable connector; (iii) affixing anadapter probe to the termination port of the separable connector,wherein the termination port is in fluid communication with a connectionport of the separable connector; and (iv) introducing a fluid throughthe adapter probe into the separable connector via the termination portfor receipt within insulation of an electrical cable inserted in theconnection port.

DESCRIPTION OF EXEMPLARY EMBODIMENT(S)

Referring now to the drawings, like parts are marked throughout thespecification and drawings with the same reference numerals,respectively. Drawing figures are not necessarily to scale and incertain views, parts may have been exaggerated for purposes of clarity.

FIG. 1 illustrates a housing of a separable connector 10. The separableconnector 10 can include a connection port 24 and a termination port 26,which can be in communication with each other to create a cavity 28. Inan exemplary embodiment, the cavity 28 can be in communication (e.g.,fluid communication) with the connection port 24 and the terminationport 26. The separable connector 10 show in FIG. 1 is an elbow connectorwhere the connection port 24 extends along a longitudinal axis A₁ andthe termination port 26 extends perpendicularly relative to theconnection port along a longitudinal axis A₂. The cavity can include asealing interface 18 corresponding to a reduced area of the cavityproximate to an elbow portion of the separable connector 10 that caninterface with a probe when the probe is inserted into the separableconnector 10 to create a seal between an outer surface of the probe andan inner surface of the separable connector 10 at the sealing interface18.

FIG. 2A depicts an example separable connector 10 (e.g., elbowconnector) configured to connect an electrical cable 12 to a powerterminal 11 of a source of energy (e.g., transformer, circuit breaker).The electrical cable 12 includes, in part, a conductive core 14surrounded by an insulation layer 16. The conductive core 14 may includeelectrically conductive strands. The electrical cable 12 may be ratedfor any medium voltage (MV) or high voltage (HV) class. The cavity 28 ofthe separable connector 10 houses the electrical cable 12 including theinsulation layer 16, the conductive core 14, a cutback gap 34, and acable connector 20, each of which can be inserted through the connectionport 24 into the cavity 28. The cavity 28 also partially houses anelectrical probe 15 or an adapter probe 50 (FIG. 2B) through thetermination port 26. The electrical probe 15 or the adapter probe 50 canbe at least partially engaged with the cable connector 20.

In an exemplary embodiment, one end of the electrical cable 12 can bereceived via a connection port 24 of the separable connector 10 and thecable connector 20 of the separable connector 10 can electrically andmechanically connect the exposed portion of the conductive core 14 ofthe electrical cable 12 to the electrical probe 15 configured to bereceived by a termination port 26 to connect the electrical probe 15 tothe separable connector 10. The connection between the electrical probe15, cable connector 20, and the conductive core 14 can be encompassed bythe housing of the separable connector 10. As shown in FIG. 2A, theelectrical probe 15 is disconnected and removed from the separableconnector 10.

In an exemplary embodiment, engagement between the cable connector 20and the conductive core 14 can produce the cut back gap 34 between thecable connector 20 the insulation layer 16 having a length measuredparallel to the longitudinal axis A1. For example, the gap 34 can have alength of approximately 1/32 of an inch to approximately 1 inch. The gap34 can, at least in part, facilitate the transmission of injection fluid(e.g., liquid, gas) for receipt by the electrical cable 12 between theconductive core 14 and the insulation layer 16, as is explained in moredetail below. The cable connector 20 can include the engagement portion22 (e.g., a threaded portion), which can be positioned in closeproximity to the termination port 26. The engagement portion 22 can beat least partially aligned with the longitudinal axis A2 of thetermination port 26. The engagement portion 22 can extend at leastpartially through the cable connector 20 so as to create a through hole.

The electrical probe 15 is configured to, at least in part, electricallyconnect the power terminal 11 to the electrical cable 12. The electricalprobe 15 can be a solid conductive rod or shaft that is inserted intothe separable connector 10, and the separable connector 10 can beinstalled over the power terminal 11 such that the electrical probe 15electrically and mechanically engages the power terminal to electricallycouple the electrical cable 12 to the power terminal 11 via the cableconnector 20. The electrical probe 15 can be removed from the separableconnector and replaced with an adapter probe, as described herein. Forexample, the electrical probe 15 can be threadingly engaged with anengagement portion 22 of the cable connector 20 such that the electricalprobe 15 can unscrewed to disengage the electrical probe 15 from thecable connector 20 and the separable connector 10.

FIG. 2B shows the separable connector 10 of FIG. 2A with the electricalprobe 15 removed and an adapter probe 50 engaged with the cableconnector 20 of the separable connector 10 in place of the electricalprobe 15. As shown in FIG. 2B, the engagement portion 22 of theseparable connector 10 can be configured and adapted to at leastpartially receive the adapter probe 50, which may include acorresponding engagement portion (e.g., a threaded portion 64 shown inFIGS. 3A and 3B) that is configured to interface with the engagementportion 22 (e.g., the engagement portion of the adapter probe 50threadingly engages the engagement portion 22 of the cable connector20). The adapter probe 50 can have a passageway 62 formed therein.During this engagement a pathway can be created that extends through thepassageway 62 of the adapter probe 50 and continues through thethrough-hole in the cable connector 20 and into the cavity 28. Theadapter probe 50 can include a groove/indent formed about an outersurface of the adapter probe 50. A sealing element, such as an O-ring21, can be disposed at a groove/indent to assist in creating anair/liquid tight seal at the termination port 26 between the outersurface of the adapter probe 50 and the inner surface of the separableconnector 10.

FIGS. 3A-B illustrate an embodiment of the adapter probe 50. The adapterprobe 50 can include a body 52 that extends along a longitudinal axis A₃a distance L₁ measured parallel to the longitudinal axis A₃ between aproximal end 58 and a distal end 60. For example, the body 52 can have alength L₁ of between approximately three (3) inches and approximatelytwelve (12) inches. The body 52 includes a cylindrical portion 68 and aconnecting feature portion 56. The cylindrical portion 68 of the body 52defines outer cylindrical surface 54, which has an outer diameter D₁,and extends a length L₃ from the proximal end to the connecting featureportion 56, measured parallel to the longitudinal axis A₃. Althoughdepicted and being described as a cylindrical portion, exemplaryembodiments of the portion 68 of the adapter probe 50 may be defined asother shapes. The connecting feature portion 56 is configured to atleast partial engage with the cable connector 20 (FIG. 2B). Theconnecting feature portion 56 can be positioned at the distal end 60 ofthe adapter probe 50 and can extend a distance L₂ from the distal end 60to the cylindrical portion 68, measured parallel to the longitudinalaxis A₃. The connecting feature portion 56 can have an outer diameterD₂, which can be equal to or less than the outer diameter D₁ of thecylindrical portion 68 of the body 52. The diameter D₂ can be sized tocorrespond to the through-hole of the engagement portion 22 of the cableconnector 20. The diameter of D₁ can be sized such that it matches, isslightly less than, or slightly greater than a diameter of the sealinginterface 18 (FIG. 1). In some embodiments, the diameter D₂ can begreater than the diameter D₁ or the diameter D₂ can vary or taper fromone end to the other. The connecting feature portion 56 can be axiallypositioned along the longitudinal axis A₃ so that it is coaxiallyaligned with the remainder of the body 52. It should be appreciated thatthe connecting feature portion 56 may be integrally formed with thecylindrical portion 68 or can be attached/fixed to the cylindricalportion 68 of the body 52. The connecting feature portion 56 can includea corresponding attachment feature to engage the engagement portion 22of the cable connector 20. For example, the connecting feature portion56 can include a threaded portion 64, which is configured to threadinglyengage with the correspondingly threaded engagement portion 22 of thecable connector 20.

Adapter probe 50 can define the passageway or through-hole 62 that canextend axially through a center of the body 52 along the longitudinalaxis A₃ to create a channel that extends from and is open at theproximal end 58 to the distal end 60 of the adapter probe 50. Thepassageway 62 can have an inner diameter D₃, which is less than D₁ andD₂. For example, the inner diameter D₃ can be between approximately 1/64of an inch to approximately ¼ of an inch. When the adapter probe 50 ismechanically engaged with the cable connector 20, the passageway 62 maybe configured to transfer fluid through the passageway and into cavity28 of the separable connector 10 or transfer fluid from within thecavity out of the separable connector 10. The proximal end 58 may befurther configured to interface with one or more fluid delivery devices(e.g., hose, pipe, fastener, conduit) and/or one or more fluid vacuum ordiscard devices.

The adapter probe 50 can define one or more sealing features/elements,such as the O-ring 21, which may be positioned with respect to at leastone surface of the adapter probe 50. For example, the sealingfeature/element may be positioned about the outer surface 54 of the body52. The sealing feature/element 66 may include an O-ring 21 for sealinga space between the adapter probe 50 and the sealing interface 18 of theseparable connector 10 to create a fluid tight seal when adapter probe50 is connected to cable connector 20 such that fluid cannot escape fromthe cavity 28 between the outer surface of the adapter probe and theinner surface of the separable connector 10. As described herein, theO-ring 21 may be positioned partially in a groove/indent 19 to, in part,assist in maintaining the position of the O-ring 21 to create a fluidtight seal when adapter probe 50 is inserted into the termination port26 and connected to cable connector 20 (FIG. 2B).

FIG. 4 illustrates a cable injection system 400. As depicted in FIG. 4,the cable injection system 400 may include at least one separableconnector 10 operable coupled to the electrical cable 12 via theconnection ports 24 and 24′, as described herein. In an exemplaryembodiment, the cable injection system 400 includes at least twoseparable connectors 10 and 10′ and the electrical cable 12 extendingbetween the two separable connectors 10 and 10′ to electrically couplethe two separable connectors 10 and 10′. In normal operation, theseparable connectors 10 and 10′ can each include electrical probes andcan be connected to power terminals 11 and 11′ of power devices (e.g.,sources of energy or loads), respectively, where the electrical probe ineach separable connector 10 and 10′ electrically connects the electricalcable 12 to each of the power devices. When fluid is to be injected intothe insulation of the electrical cable 12, which may be buriedunderground or otherwise inaccessible, one or both separable connectors10 and 10′ can be removed from the terminal(s) of the power device(s)and the electrical probe(s) can be removed. The adapter probes 50 and50′ can be inserted into the termination port(s) 26 and 26′ of theseparable connectors 10 and 10′, respectively, in place of the removedelectrical probe(s). For example, as shown in FIG. 4, in a non-limitingconfiguration, one of the adapter probes 50 is coupled to the separableconnector 10 and one of the adapter probes 50′ is coupled to theseparable connector 10′. The adapter probes 50 and 50′ are inserted intothe termination port(s) 26 and 26′ of the separable connectors 10 and10′. The separable connectors 10 and 10′ with the adapter probesinserted therein can be placed in fluid communication with a feed tank402 and a discard tank 408 by way of fluid conduit 405 and 310,respectively. The feed tank 402 can be filled with fluid to be forcedinto the electrical cable 12 under pressure and/or the discard tank 408can be under vacuum pressure to draw the fluid from the electrical cable12.

For illustrative purposes, the feed tank 402 can be a supply tank anddiscard tank 408 can be a waste tank. The feed tank 402 can be in fluidcommunication with the electrical cable 12 via the fluid conduit 405,which can be in direct or indirect communication with the adapter probe50, and the adapter probe 50 can be in direct or indirect contact withthe separable connector 10. Particularly, the feed tank 402 can includeone or more valves/fittings 404 that are in fluid communication with thefirst fluid conduit 405. The discard tank 408 may be in fluidcommunication with electrical cable 12 via the fluid conduit 310, whichcan be in direct or indirect communication with the adapter probe 50,and the adapter probe 50 can be in direct or indirect contact withseparable connector 10′. Particularly, the discard tank 408 may includeone or more valves/fittings 410 that are in fluid communication with thefirst fluid conduit 310.

Injection fluid 406 stored in the feed tank 402 can be injected into theelectrical cable 12. The injection fluid 406 can be injected into theelectrical cable 12 between the insulation layer 16 and the conductivecore 14 under pressure via the adapter probe 50 of the separableconnector 10. The fluid can be injected at varying pressures (e.g., 0.2MPa to 0.4 MPa). The injection fluid 406 can pass through the adapterprobe 50 of the separable connector 10 and into the cavity 28 of theseparable connector 10. The injection fluid 406 may come in contact withthe cable connector 20, the cavity 28, the gap 34, the conductive core14, and/or the insulation layer 16. As the above-mentioned the injectionfluid 406 passes through the electrical cable 12 and exits out of theseparable connector 10′ (e.g., via the adapter probe 50 inserted intothe separable connector 10′. Shown, as discard fluid 412, the injectionfluid can come in contact with the insulation layer 16, the conductivecore 14, the gap 34, the cavity 28, the cable connector 20, and theadapter probe 50 in the separable connector 10′ before being outputthrough the fluid conduit 310 and discharged into the discard tank 408.The injection fluid 406 can pass through the electrical cable 12 and mayinclude water and other residual fluid (e.g., injection fluid) presentwithin the electrical cable 12 and as such may become discard fluid 412.

FIG. 5 is a flowchart illustrating an example process of injecting afluid into an electrical cable. While the process of using the adapterprobe 50 is described with reference to the cable injection system 400,it should be appreciated that exemplary embodiments of the adapter probe50 are not limited to the assembly or configuration described withreference to FIG. 4. The process described herein with reference to FIG.5 is merely illustrative of one of the many potential uses for theadapter probe 50.

At step 500, an electrical cable (e.g., electrical cable 12) isidentified for receiving injection of a fluid (e.g., based on whetherthe electrical cable meets minimum criteria to inject a fluid andelectrical test determines no insulation defects are present). At step502, separable connectors (e.g., separable connectors 10) connected tothe ends of the electrical cable are disconnected from electricalterminals of power devices. At step 504, electrical probes (e.g.,electrical probes 15) are removed from separable connectors (e.g., fromtermination port 26 of separable connector 10). At step 506, adapterprobes (e.g., adapter probe 50) are inserted into the separableconnectors in place of the electrical probes at each end of theelectrical cable. At step 508, an injection fluid (e.g., liquid, gas406) is introduced through one of the adapter probes at a first end ofthe electrical cable into separable connector for receipt within theelectrical cable. At step 510, the injection system (e.g., injectionsystem 400) is monitored for injection fluid receipt within theelectrical cable and discard fluid (e.g., discard fluid 412) dischargedat a discard tank (e.g., discard tank 408) at a second end of theelectrical cable. At step 512, upon completing the injection of fluidinto the electrical cable, the injection system is removed and theadapter probes are removed probes. At step 514, the electrical probesare reinstalled back into separable connectors (or new electrical probesare installed). At step 516, the separable connectors with theelectrical probes are reconnected to electrical terminals of the powerdevices.

Further, in operation, separable connector 10 may be configured toconnect sources of energy (e.g., transformer, circuit breaker) viaelectrical cable (or cable section) 12. The sources of energy interfacewith a probe positioned within the termination port 26 of the separableconnector 10. To begin, the separable connector 10 is removed from apower terminal 11. Then, the probe is removed from separable connector10. In some instances, probe may be engaged with the cable connector 20,which is further engaged with the electrical cable 12. The probe may beunscrewed from the cable connector 20, however, additional removaltechniques may be used. The above can be repeated as necessary forremaining separable connectors 10, if any. Then, with the source ofenergy disconnected, engage the adapter probe 50 at least partially withthe separable connector 10 (e.g., termination port 26), as discussedherein. Particularly, the adapter probe 50 may be at least partiallyinserted into termination port 26 and even more particularly, adapterprobe 50 may be threadingly engaged with termination port 26 and/orcable connector 20. The above can be repeated as necessary for remainingseparable connectors 10. Affix one end of the one or more fluid conduitsto the adapter probe 50 and the other end to one or more fluid tanks(e.g., feed tank, discard tank). For example, affix the first fluidconduit 405 to the first adapter probe 50 which is in communication withthe electrical cable 12. Then, affix the second fluid conduit 310 to thesecond adapter probe 50′, which is in communication with the electricalcable 12 and the first adapter probe 50. Inject an injection fluid fromthe feed tank 402 into the first fluid conduit 405 into the electricalcable 12. Injecting the injection fluid can force discard fluids (e.g.,water, residual fluid) that are within the electrical cable 12 into thediscard tank 408 by way of second fluid conduit 310. Once satisfied withthe injection process, disconnect the necessary injection components andattach the probe to the separable connector 10 and to the power terminal11, as known in the art and outlined above with respect to the removalof probe.

FIG. 6 illustrates another embodiment of an adapter probe 50A. Theadapter probe 50A. The adapter 50A can define a first adapter body 52Aand a second adapter body 113. The first adapter body 52A can beidentical to the body 52 of the adapter probe 50 except that a proximalend of the first adapter body 52A is operatively coupled to the secondadapter body 113, which extends perpendicularly with respect to thefirst adapter body 52A. The proximal end of the first adapter body 52Ainterfaces with the second adapter body 113 at approximately the middleof the length of the second adapter body 113 such that the adapter probe50A has an T-shaped configuration.

The first adapter body 52A can define the passageway or through-hole 62described herein. The second adapter body 113 can define a passageway orthrough-hole 124 that may extend axially through a center of the body113 along the longitudinal axis A₄ to create a channel. The passageway62 of the first adapter body can be open at the proximal end and distalend and can be in fluid communication with the passageway 124 of thesecond adapter body 113. In some embodiments, one end of the secondadapter body 113 can be capped or closed to terminate the passageway124. In some embodiments, both ends of the second adapter body 113 canbe open to the passageway 124. An open end of the second adapter body113 can be configured to interface with one or more fluid carryingdevices (e.g., hose, pipe, fitting, conduit) for introducing fluid intothe passageway 124 and passageway 62 or for receiving fluid from thepassageway 62 and passageway 124. For example, the adapter probe 50A canbe configured to provide fluid, through the passageways 124 and 62 tothe electrical cable 12 when the adapter probe 50A is inserted into thetermination port of separable connector 10 and the electrical cable isinserted into the connection terminal of the separable connector 10.

FIG. 7 illustrate another embodiment of an adapter probe 50B. Theadapter probe 50B can define a first adapter body 52B and a secondadapter body 218. The first adapter body 52A can be identical to thebody 52 of the adapter probe 50 except that a proximal end of the firstadapter body 52A is operatively coupled to the second adapter body 218,which extends perpendicularly from the proximal end of the first adapterbody 52B such that the adapter probe 50B has an L-shaped configuration.

The first adapter body 52B can define the passageway or through-hole 62described herein. The second adapter body 218 can define a passageway orthrough-hole 226 that may extend axially through a center of the secondbody portion 218 along the longitudinal axis A₁ to create a channel. Thepassageway 62 of the first adapter body 62 can be open at the proximalend and can be in fluid communication with the passageway 226 of thesecond adapter body 218. An open end 220 of the second adapter body 218can be configured to interface with one or more fluid carrying devices(e.g., hose, pipe, fitting, conduit) for introducing fluid into thepassageway 226 and passageway 62 or for receiving fluid from thepassageway 62 and passageway 226. For example, the adapter probe 50B canbe configured to provide fluid, through the passageways 226 and 62 tothe electrical cable 12 when the adapter probe 50B is inserted into thetermination port of separable connector 10 and the electrical cable isinserted into the connection terminal of the separable connector 10.

FIG. 8 illustrates another embodiment of an adapter probe 50C. Theadapter probe 50C can at least partially engage with the terminationport 26 of the separable connector 10 when the electrical probe isremoved. The adapter 50C can be a plug formed of a resilient material,such as a polymer (e.g., rubber). The plug can have a generallytruncated cone configuration, where a proximal end 312 forms a base onthe truncated cone. A diameter of the plug can be at least partiallytapered radially inwardly along from the proximal end 312 to a distalend 314. The adapter 50C can further define the passageway 308 that canextend between and open to the proximal end 312 and distal end 314. Inan exemplary embodiment, the passageway 308 can extend through a centralaxis of the adapter probe 50C. The adapter probe 50C and passageway 308can be configured to interface with one or more fluid carrying devices320 (e.g., hose, pipe, fitting, conduit) to introduce fluid into thepassageway 308 or for receiving fluid from the passageway 308. Forexample, the adapter probe 50C can be configured to provide fluid,through the passageways 308 to the electrical cable 12 when the adapterprobe 50C is inserted into the termination port of separable connector10 and the electrical cable is inserted into the connection terminal ofthe separable connector 10.
